-I Identify program and exit.
-i item Select first item matching item specification.
-a type Select all items matching item specification.
-g spitem Select a speech item for display as a spectrogram using on-line FFT.
-G opt Control of spectrogram display. Argument is made from these letters: 'S' = display speech signal, 'W' = display wideband, 'N' = display narrowband. This applies to all speech items displayed.
-s start Specify a start time (in seconds) other than 0.0.
-e end Specify an end time (in seconds) other than the length of the first speech item in the file. If no speech item found, default timescale is 1 second.
-f "item lo hi" Fix all displays of a given type to the y-range lo..hi.
-l labelname Select labelling mode: an annotation editing facility. The annotations to be edited must be given a name (labelname) that is stored in the history for the annotation data set. If any existing annotation items in the file have the same name (i.e. with "type=<name>" in the history field), the last is used as the initial contents of the annotation data set.
